COIN-OPERATED INDUCTION-COIL.

SPECIFICATION forming part of Letters Patent No. 399,591, dated March 12, 1889.

Application filed scptember 1, 1888. Serial No. 284,373. (No model.)

To all whom, it may concern.-

- Be it known that we, PERCY G. \VILLIAMS and ALFRED \v'. ROOvERs,both of the city of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful lmprovemtmt in Coin-Operated Induction-Coils, of which the following is a specification.

Our improvement relates to that class of i0 machines in which a coin of given weight and size is employed to energize an induction-coil in such manner that an electric current will be transmitted through electrodes to a person grasping and operating said electrodes.

o will describe a coin-operated induction-coil embodying our llllPl'OVQillOllil in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure 1 a rear elevation of a machine embodying our in'iprovement, the back and sides of a casein which the same is contained being removed and a portion of the case being broken away to save space. Fig. 2 is a view similar to Fig. 1, except that the parts are shown in a different position from that which they occupy in Fig. 1. In this view a certain portion of the mechanism is broken away to save space. Fig. 3 is a horizontal section of the machine, taken on the plane of the line 1 y, Fig.1. Fig. -i is a horizontal section taken on the line .2 .2, Fig. 1. lrig. 5 is a vertical section taken on the line a; 3, and looking in the direction of the arrow. Fig. 6 is a detail showing certain trip mechanism.

Similar letters of rei'erei'lce designate corresponding parts in all the figures.

A designates the induction-coil. This coil may be of the usual construction. In the example of our improvement shown a metallic shell, u, surrounds the secondary of the intlllChlOi'l-(jOll. This shell is capable of being moved longitudinally on the induction-coil. Such movement is accomplished by means of a rod, a, secured to one end of the shell. The rod extends through a suitable aperture in the case A, in which the machineis inclosed. U )on the rod outside the case is a handle, A constituting an electrode. W'hen this handle is grasped and drawn outwardly, the

shell a will be moved longitudinally on the induction-coil. The purpose of moving the shell longitudinally on the induction-coil is to increase or decrease the secondary current, as may be desired. hen the shell has been moved outwardly by means of the handle, we have shown a convenient means for returning it to its normal position, consisting in a weight, A which. weight has connected to it near its upper end a cord or chain, a which cord or chain passes over a pulley, a, mounted upon a frame, a which frame is secured to the case A of the machine, and constitutes, likewise, a support for the iiuluction-coil. The cord a after passing over the pulley, extends to near the forward end of the rod a, and is socured thereto in any suitable manner. It will be readily seen that when the force tending to draw the handle A and the shell outwardly is removed the weight A will operate to restore the parts to their normal position.

A" designates a handle constitutingan electrode, which handle is similar to the handle A except that in this example of our improvement it is not longitudinally movable, but is rigidly secured to the case of the machine. lVe have shown it as insulated from the case of the machine, the latter being preferably made of metal. -A wire, of, extends from the secondary of the inductioncoil to the handle A. Circuit is closed on the secondary of the induction-coil when the two electrodes are grasped. The person grasping them will therefore receive an electric shock upon withdrawing the handle A The mode of energizing the induction-coil will be presently described.

As previously stated, the induction-coil is energized and the machine rendered operative by means of a coin of certain size and weight. This coin is passed inwardly to a slot, b, in the case A and passes into a chute, B, by which it is conducted downwardly. Ye have shown the chute B as provided with an angular portion or bend near its lower extremity, whereby the coin before passing out of the chute will pursue a circuitous course. This construction prevents the introduction of any instrument by which the coin might be withdrawn after having been once passed through the chute. The coin,

after leaving the chute, falls into a receiver, B. This receiver in the example of our improvement shown consists of a pan or cup made of two sections hinged together at their upper edges. The sections of the receptacle are of such weight near their lower extremities that they will, when the receptacle occupies a normal position, or that position which is shown in Fig. 1, remain in contact, so as to close the receptacle. We have, however, shown means for securing them in such position and occupying a normal position, consisting of lugs 1), extending from the exterior of the receptacle. These lugs, when the receptacle is closed, are substantially in contact. They are retained in such position by means of a combined closing and opening device, W. This device comprises, essentially, a lever fulcrumed upon a second lever, B The portion of the closing and opening device 19 adjacent to the receptacle B is provided upon its under side with a tooth, 19 This tooth is so formed upon the opener and closer that when the latter occupies a normal position, or that shown in Figs. 1 and 2, it extends downwardly about the lugs b, so as to operate as a lock to secure the parts of the receptacle together. On the outer end of the closer and opener b and beyond the teeth 79 the same is provided with an upwardly-extended hook, I). Extending from that section of the receptacle adjacent to the hook b is a pin or projection, b. When the closer and opener b is rocked upon its fulcrum out of a normal position, as shown more clearly in Fig. 6, the hook b will engage the pin 19 and cause the opening of the receptacle. WV'hen the receptacle is open, the previously-contained coin will fall into a receiver, S, located beneath it. The receptacle is provided in its bottom with an aperture, (here shown as circular,) which is of such diameter as not to admit of the passage of a coin of the proper size when the receptacle is closed, but which will allow a coin of smaller size than is proper to pass through into the receiver S.

The receptacle B is mounted upon the lever B near one end of the latter. This lever is fulcrumed upon an arbor, b, journalled at one end in a rigid bracket, 0, extending from the case A, and also in a set-screw, 19 having a screw threaded connection with a downwardly-extending portion of the bracket 0. By this means a very delicate movement of the lever B and consequently of the receptacle B, may be secured. Upon the lever B at the portion opposite to that upon which the receptacle B is mounted is arranged a sliding weight, I)", provided with a setscrew, by which it may be secured in any desired position on the lever. This weight operates to restore the lever B and the receptacle B to their normal positions after a coin has been ejected from the receptacle. A stop, 19 consisting of a pin extending from the bracket 0, prevents the weight b from rocking the lever too far in one direction. A coin having been dropped into the receptacle B and the lever B being rocked downwardly thereby, circuit is closed on the primary of the induction-coil.

D designates an electric battery. From the battery a wire, (1, extends to a contact-piece, cl, consisting, as hereshown, of a spring-finger mounted upon but insulated from the bracket 0. Upon the lever B is a projection, d When the lever is rocked by means of the coin, the projection d contacts with the contact-piece d. From the battery D extends a wire, (1 to a vibrator upon the inductioncoil. From the vibrator extends a wire, d, to one pole of the'primary. From the other pole of the primary extends a wire, 01, to a rocking piece, J, comprised in certain time mechanism to be presently described. The rocking piece J is in contact when circuit is to be closed with a resilient contact-piece, d, mounted upon but insulated from a bracket, 0, secured to the case of the machine. From the contact-piece d a wire, 01 extends to the bracket 0. It will therefore be seen that when the coin has been deposited in the receptacle B and the lever B has been rocked, so as to make contact with the contact-piece D, circuit will be closed, which includes the battery D, the wire (1 the primary of the inductioncoil, the rocking piece J, the contact-piece d, the wire (1 the bracket C, the contact-piece d, and the wire d. Circuit having been closed, the person desiring to test the machine grasps the electrodes A A and withdraws the electrode A whereupon he receives a shock, as previously described. Unless a coin has been deposited in the receptacle B and the lever B rocked, the handle A may of course be withdrawn without any current being experienced. The weight A Will also be merely lifted up and down without in any way affecting any of the more delicate parts of the machine. When, however, a proper coin has been dropped in the receptacle, the raising of the weight A causes the operation of certain other parts of the machine, which we will now proceed to describe.

H designates an arm rigidly mounted upon a rod, H. This arm extends approximately horizontally in two directions from the rod H. Its extension in one direction is provided near itsouter end with avertically-extending aperture, 6, through which the weight A when the lever B occupies a normal position, may move up and down freely. When, however, the lever B is rocked by the coin, a lock between the arm H and the weight A is formed. This is accomplished in the following manner:

H designates a dog pivoted upon a downward extension from the arm H. Extending from the dog is a projection, 8. Upon the lever B is a pin or projection, 6 The projection e on the dog extends into the path of the pin or projection 6 when the latter is moving upwardly during the rocking of the lever B The pin 6 therefore contacts with is another collar,

the projection e on the dog and rocks the latter in such manner that it will engage an annular groove, a", formed in the weight A. A lock is thereby formed between the arm II and the weight A", whereby when the weight A is elevated the arm II will be caused to move upwardly with it. The arm ll being rigidly secured to the rod II, when the former is moved upwardly, it causes an upward 1. Also adjustably secured upon the rod ll is a collar, f Surrounding the rod ll at each end of the collarf' are elastic bumpers f f preferably of rubber. The bumpers for the weight f, and also for the collar f prevent jarring of parts owing to the sudden raising or lowering of the rod ll. Above the bumper This collar is not secured to the rod 1], but may slide freely thereon. lletween the collar and the weight f is arranged a coil-spring, j', which latter surrounds the rod II. The collar is provided with a projection, f Extending from the projection f and at ap n-oximate right angles thereto is a pin, f As shown, this pin extends through an aperture in the projectionf and is adjustably secured therein by means of a set-screw, f. \Vhen the parts occupy a normal positionas, for instance, that shown in Fig. 1the pin f rests upon an arm, j, of the rocking piece J. \Vhen the rod ll is elevated by means of the arm H and weigl'lt A", the pin is moved away from the rocking piece J, whereby certain time mechanism presently to be described permitted to operate. If the rod ll descends too rapidly, the coil-spri ngj will yield to allow the collarf to move upwardly upon the rod 11, so that the pin f will not strike the arm j a violent blow, which might break or disarrange the parts. The upward movement of the rod l'l also causes the upward movement of a rod, L, which rod extends through suitable apertures in a portion of the arm if and parallel with the rod II. It is maintained friction-tight in said aperture by means of a fiat spring, I, secured to the arm II and bearing against said rod. The rod L has secured to it near its lower end a trip, L. This trip is approximately bell-cranked in shape. The object of this trip is to open the receptacle l3 and to cause the coin to be ejected therefrom. The construction is such and the operation so timed that a very slight reverse or inward movement of the electrode A would cause the trip L to open the receptacle, drop out the coin, rock the lever B into its normal position, and thus break circuit.

The operation is as follows: It will be observed that the inner end of the closing and opening device b is beveled on its under side. The lower arm of the trip L has a portion, l bent at approximately right angles thereto and extending toward the lever '3 Vhen the rod L is elevated by the rod II, the portion Z of the trip comes in contact with the beveled portion of the opener and closer b and is rocked upon its pivot, so as to pass by the opener and closer. It then swings by gravity into the position shown more clearly in Figs. 2 and 6.

It will be readily seen that when the rod L is lowered the portion 1 of the trip will contact with the opener and closer 12*, rock the latter upon its fulcrum, and cause the opening of the receptacle, as previously described. This operation is shown more clearly in Fig. ('3. hen the receptacle has been fully opened, as shown in the latter figure, it is of course desirable to cause the trip to pass by the opener and closer. To do this we provide a stop, Z extending from and secured to the portion Z) of the bracket C. An arm, F, on the trip L will, when the parts have reached the position referred to, come in contact with the stop I, and any further downward movement of the rod L will cause the trip to be rocked on its pivot and pass by the opener and closer 12 The latter then of course returns to its normal position and the receptacle is again closed.

Ye have shown spring-fingers Z secured to the rod L near its upper end and surround ing the rod ll. These fingers act as steadiments. Only a limited movement is permitted the rod L, or a movement only sufficient to cause the trip to pass wholly beyond the opener and closer A too extended upward movement of the rod is prevented by the contact of the upper end of said rod with the bracket C. The arm 11 may then slide freely by upon the rod L, following the movement of the rod ll. The stop I performs another function than that describednamely, it operates as an abutment to prevent a too extended downward movement of the rod L. Therefore when the portion 1 of the trip is in contact with the stop 7 the arm ll may slide freely downwardly upon the rod L, following the movement of the rod ll. It will therefore be seen that the range of movement ofthe rod L is very slight.

\Ve desire to limit the time during which an electric shock may be received by a person operating the machine. For this purpose we provide time mechanism. Such time mech anism consists of a weight, F, suspended from a cord, g This cord is wound upon a drum, g. Said drum is rigidly mounted upon a shaft, g mounted in a suitable frame secured, as here shown, to the bracket 0. Loosely mounted upon the shaft is a gear-wheel, g

which gear-wheel meshes with a gear-wheel, 9 mounted on a shaft, 9 Upon the shaft g is mounted another gear-wheel, g, which gear-wheel meshes with the gear-wheel 9 mounted on a shaft, 9 Upon the shaft g is mounted another gear-wheel, g", which gearwheel meshes with the gear-wheel 9 mounted on the shaft g. Upon the outwardlyextending end of the shaft 9 is a fan, g by which the time mechanism is regulated. The gear-wheel g is provided with a pawl, 9 engaging a ratchet, g, in order to cause the rotation of the gear-wheel 9 when the shaft 9 is rotated in one direction, in a well-known manner.

The rocking piece J is provided near one end with a segment-gear, G, gearing with a gear-wheel, h, mounted on the shaft 9 When the rocking piece J is rocked into one position, it operates to wind up the weight. This operation is performed by the pin f con tacting with the arm j of the rocking piece J, and rocking the latter during the downward movement of the rod H, in the manner previously described. When the rod H is elevated, and the pin f consequently moved out of contact with the rocking piece J, the weight F then causes the reverse rotation of the parts and the consequent rocking of the rocking piece J in the other direction.

It is to be borne in mind that the primary circuit is closed by means of the contact of the rocking piece J with the contact-piece d". It will be seen that the latter is bent or deflected at an upward angle near its upper end. When, therefore, the rod H is elevated and the arm j of the rocking piece J is moved upwardly, the latter, upon reaching the bent or deflected portion of the contactpiece d, of course breaks contact therewith, and consequently breaks the circuit. No further current can therefore be received by the person manipulating the electrodes.

As previously stated, the downward movement of the rod H rewinds the time mechanism by means of the contact with the pin f, with the arm j, or the rocking piece J.

We have shown the upper portion of the rod H bent over upon itself and provided upon the inner edge of the bent-over port-ion with a rack, N, which rack engages a pinion, N, mounted upon a shaft, N extending from an upwardly-extending portion of the bracket 0 Outside the case is a dial of any ordinary construction, which I have not shown in the drawings. The shaft N extends to the dial and has mounted upon it any suitable pointer. WVhen the rod H is moved upwardly, the rack causes the rotation of the pinion, and consequently the movement of the pointer about the dial to indicate the degrees of strength of current which the operator is receiving.

We have throughout the specification referred to the operation of the machine as being upon closed circuits; but it is of course quite obvious that it could be as easily operated upon an open circuit by any of the wellknown methods.
